HOOD FASTENER Application filed October 9, 1929. Serial No. 398,407.

This invention relates to certain new and useful improvements in means of fastening primarily designed fonapp'lication upon the hoods of. motor vehicles to prevent theft by 5 unscrupulous persons through access to the wiring.

Another object of the invention contemplates a remote cpntrol operating mechanism arranged within the vehicle within reach of river. An additionalobject of the invention con- Y sists in the provision and arrangement of means whereby the fastening devices may be the hood to prevent tam- Figure 1 is a fragmentary side elevation,

of a motor vehicle with the hood andcowl therefor partly broken away to illustrate the arrangement of the invention.

Figure 2 is a vertical sectional view taken on line 2-2 of Figure 1 showing the dual arrangement of the fastenings. Figure 3 is an elevation of one ofthe fastenings unlatched. Figure 4 is a view similar toFigure 3 in locked position. s Figure 5 is a longitudinal sectional view taken throughthe invention on line 55 of Figure 4.

Figure'6 is a perspective view of a form ,of guide-employed for the beaded or rolled" edges of the hood sections to guide the means of fastening into position for connection with the locking mechanism. a

Referring to the drawings in detail, wherevin like characters of reference denote corresponding parts, the reference'character 1O indlcates generally a motor vehiclehaving a hood 11 with hingedly mounted side sections 12 and'13. The depending edges of the sections are beaded or rolled, as at 14, in the conventional manner.

In carrying out the invention, I provide plunger cylinders 15 open at their upper ends 5 and provided with restricted guide openings in their lowermost ends to accommodate plunger shafts 16. Pistons or plungers 17, carried by and adjustably mounted upon the uppermost projecting ends of the plunger shafts 16 within the plunger cylinders 15 engage the adjacent ends of compression springs 18 located within the plunger cylinders and seated at their opposite ends upon the solid portions of the lowermost 'apertured ends of the plunger cylinders, substantially as illustrated in Figure 5 of the drawings. As shown, the plunger shafts terminate to provide eyes or loops, indicated as at 19, and which may be shaped in any desired manner. to accommodate a form of locking mechanism found best adaptable to the purpose. The present-form of'eyes or loops are of elongated formation and vertically disposed,

the purpose of this especial shape will be presently brought out in the description of the invention to follow.

Bracket members, such as indicated at 20, of substantial U-shape formation, are arranged upon the sills or flanges of the I-beam or channel forms of motor vehicle chassis construction. Cams 21, swingably "mounted upon pivot pins 22 supported terminally thereof by the upstanding parallel arms of the brackets 20, are provided with curved locking fingers 23 designed for reception within the enclosures of the eyes or loops 19 when same are swung from the Figure 3 to the Figure 4 positions. This action is accomplished through the provision and arrangement of levers 24 eccentrically mounted upon the pivot pins 22 and lock ingly engaged with the cams-'21 at their shorter ends and in remotely disposed relation to'that of the curved locking fingers 23. Two of these look fastenings are to be employed upon ealchsection'of the vehicle hood and for this reason drag links 25 common to each pair are employed. Cle'vis yoke connections may be provided between the ends of the levers 2A and drag links.

Plate members 26, arranged beneath and spacing the attaching potions of the brackets'v 20 from the chassis or frame of the vehicle, are rovided with outwardly promoting ears 2? having upwardly and o liquely disposed extremities 28. These extremities are'desi'gned to engage and guide the rolled or beaded edges 14 of the hood sections 12 and 13 downwardly and inwardly whereby the enclosures of the loops or eyes in the plunger shafts 16 will be disposed in position whereby the locking fingers 23 may be effectively passed therethrough;

As mentioned in the foregoing the locking or fastening means are to be controlled from within the driving compartment of the vehicle and in accomplishing this end it is my intention to employ forms of lever members 29 having eccentric pivot connections 30 upon the projecting portions of suitable forms of anchorage, indicated as at 31. Pull or throttle rods 32 establish connection at their ends with the rearmost or adjacent of the coupled levers 24 and the shorter ends of the lever members 29, When the latter mentioned levers are shifted to occupy positions whereby the locking fingers 23 of the vcam memof motor vehicles comprising plunger cylind'ers mounted upon the inner sides thereof, compression springs carried within said, cylinders, plunger shafts extended within the ends of the cylinders having the plungers thereof engaging with said springs mally retract the same therein, saidshafts formin eyes within the outermost project-- ing en s thereof, locking means swm ably mounted upon stationary portions 0 the motor vehicle adj acent said eyes, locking fingers carried by the locking means designed for reception within the enclosures of said eyes,

mountings of-th'e locking means having ears outwardly projecting'therefrom beneath the edges of the hood sections and opposite the cylinders and locking fingers, and said ears having the extremities therefor upwardly and obliquely inclined to :enga e and guide the aforementioned edges of t e hood sections in position whereb the-eyes and fingers may coincide for loc ing engagement.

In testimony whereof I afiix my signature.

bers 21 will be passed through the enclosures of the eyes orloops 19, the plunger shafts 16 will be withdrawn for appreciable distances without the plunger cylinders 15 whereby the tension of the springs will be caused to act upon the locking fingers 23 to hold the assembly against rattling and such spring action will coact with the ofl' center position of the end of the throttle rod 32 having connection with the shorter end of Stops, such as indicated at 33 and of angular formation, are arranged adjacent the ends of the motor vehicle instrument panel and upon the depending edgb therefor for contacting engagement with the longer-ends of the lever members 29. 'The tension of the compression springs will yieldingly retain the aforementioned longer I ends of the lever members 29 against the adjacent portions of the stops 33. i

As understood from the description of the I invention and the illustrations thereof, principally in Figures '1, 2and 5 of the drawings, the fasteningsare to be enclosed by the sections of the hood to prevent unscrupulous persons from tampering with the devvice or having access to the wiring of the vehicle.

The invention is. susceptible of various changes lnits form, proportions and minor details of construction and the right is herein reserved to make such changes as properly MICHAEL H. MAROHNER.
